Enhance image contrast using min(1,x$anindex/contrast.enh instead of the anisotropy index itself. Effective values are within the interval (0,1).

what

In case of class "dtiIndices"what="ga" uses geodesic anisotropy (GA) in contrast to what="fa" for fractional anisotropy (FA). For class "dwiMixtensor"what="fa" for FA and what="order" for the number of mixture components may be chosen.

mar

Graphical parameter for par.

mgp

Graphical parameter for par.

qrange

Cut image intensity to these quantiles to avoid that outliers determine the dynamic range of the image.

xind

If provided restrict display to indices specified in xind for x-direction.

yind

If provided restrict display to indices specified in yind for y-direction.

zind

If provided restrict display to indices specified in zind for z-direction.

Methods

x = "ANY"

Generic function: see plot.

x = "dwi"

Returns a warning.

x = "dtiData"

gradient can be used to specify a specific data cube associated with the index of a gradient direction. For objects of class "dtiData" images are produces that are scaled by the maximal observed image value. This guarantees that subsequently produced images are on a comparable grey scale. The resulting image of class "adimpro" from package adimpro is returned.

x = "dtiIndices"

Color coded anisotropy maps are produced depending on the specification in method. method==1, method==2, method==4 and method==5 specify three different color schemes for directional FA-maps. method==6 uses colored FA maps based on scheme developed at Uni Muenster (M. Deppe, Germany). method==3 specifies visualization of dtiIndices using color coded shape parameters. If identify==FALSE the resulting image of class "adimpro" from package adimpro, otherwise a matrix with coordinates of identified voxel is returned.
